Use only for webp conversion

I’m wondering if this plugin can be configured so it only does WebP conversion. I have a plugin I’m already happy with for jpg compression, and as Optimus doesn’t let me configure the JPG compression level, I’d prefer to keep using my existing plugin for that. I do need a plugin that will do WebP conversion though, and wonder if this might be it.

If it’s available as an API call I’m happy to look into that as well 🙂
